Question- Calculate the mass of barium chloride you need to make a .200 m barium chloride solution with 100.0g of water. Show the computation
At 25 °C, water has an equilibrium vapor pressure of 23.8 mm Hg. If 2.500 g of water is sealed in an evacuated 10.0-L flask and heated to 25 °C, what mass of water will evaporate?
More gas is then added to the container until it reaches a final volume of 13.9 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
In which of the processes described below should the entropy increase. Choose ALL of the correct possibilities. A) ice cubes melting at -5 oC and 1 atm pressure
At a certain temperature and pressure 2.1 L of H2 reacts with 2.1 L of I2. If all the H2 and I2 are consumed, what volume of HI, at the same temperature and pressure, will be produced?
Suppose you have 260.0 mL of a 0.320 M NaC2H3O2 solution. You add 260.0 mL of a 0.320 M HCl solution to it. What is the new pH. If you added an additiional 40.0 mL of a 3.20 M HCl solution to the aboe solution, what is the new pH.
The activation energy of a certain reaction if 65.7kJ/mol. How many times faster will the reaction occur at 50 degrees Celsius than at 0 degrees Celsius? State the assumptions you need to make in order to perform this calculation.
if iodine gas reacts with excess fluorine gas to produce 7.575 g of iodine penta fluoride gas, what was the pressure of the iodinee gas before reacting if it was kept in a 1.5L flask at 298 k
